This invention relates to the field of data processing and discloses a database log archiving method, apparatus, device, and medium, comprising: identifying a target redo log file to be archived from the database; creating a preliminary redo log file with the same attributes as the target redo log file and empty content within the same logical disk as the target redo log file; moving the target redo log file to a preset archiving directory located within the same logical disk via MV operations; changing the filename and storage path of the preliminary redo log file to the original filename and storage path of the target redo log file via MV operations; and mounting the revised preliminary redo log file to the database. This invention solves the problems of high I / O consumption and low archiving efficiency in existing database log archiving technologies.

The application belongs to the technical field of artificial intelligence, and particularly relates to a method for accelerating file reading based on Kubernetes, which comprises the following steps: obtaining a training task; adding a data set of the training task to a cache file system; increasing the reference times of files in the data set of the cache file system and updating the latest time dynamics; mounting the cache file system to a POD container; reading the data set by establishing a script in the POD container and performing task training on the read data set; reducing the reference times of files in the data set after training; and judging the reference times of the files in the data set after training, and cleaning the corresponding files when the reference times are lower than a preset number threshold or the idle time is greater than a preset time threshold. The application mainly solves the problem of slow data reading caused by low-speed storage in the model training process.
